System M+ is a self-closing, fully adjustable pivot hinge system engineered for doors from 20 kg to 500 kg. Concealed inside the door and floor, it provides complete control over every part of the door's movement through three independent adjustment systems. No visible frame, no overhead closer — just a door that moves exactly as specified.

Damper Control provides adjustable hydraulic resistance on both opening and closing. On opening, a hydraulic back-check slows the door as it approaches 70° to protect walls. On closing, it delivers a smooth, controlled soft-close through the full arc of travel.

30° Speed Control governs the final phase of closing independently, ensuring the door always returns to position gently regardless of how fast it was opened or released.

Latch Control adjusts the latching force in the last degrees before closed position, guaranteeing reliable engagement of latching bolts every time. Essential for exterior doors and any door with a mortise lock.

The system is self-closing from 125° and −125°, with hold positions at 0°, 90°, and −90°. Single and double-acting configurations are available. The radial closing angle is adjustable up to 5°, and axial adjustment of ±5 mm is available from the top pivot.

The backset determines where the pivot point sits relative to the edge of the door. All three options use the same bottom pivot mechanism and are available across all weight classes.

	70 mm Backset	40 mm Backset	TP-R (Top Pivot Reversed)
Pivot point	Flexible — from 70 mm to centre of door	Fixed at 40 mm from door edge	Reversed — pivot mechanism at top of door
Cover plates	Not available	Included — stainless steel or black	Included — stainless steel or black
Best for	Most residential and commercial installations. Greater flexibility in pivot placement.	Narrower doors, maximum clear opening, ADA-compliant widths from a standard slab.	Installations where floor routing is not possible or where top-access servicing is preferred.
System dimensions (Class AA–E)	294.8 × 32 × 99.6 mm	272.7 × 32 × 149.6 mm	Per TP-R specification
System dimensions (Class F–G)	308.2 × 42 × 112.7 mm	284.7 × 42 × 169 mm	Per TP-R specification
Depth in door (Class AA–E)	100 mm	150 mm	Per TP-R specification

Weight class is determined by both door weight and door width. All three configuration options are available across all eight weight classes.

Class	Door Weight	Series	Min. Door Thickness
AA	20 – 79 kg	M32+	40 mm
A	80 – 119 kg	M32+	40 mm
B	Up to 159 kg	M32+	40 mm
C	Up to 209 kg	M32+	40 mm
D	Up to 279 kg	M32+	40 mm
E	Up to 349 kg	M32+	40 mm
F	Up to 429 kg	M42+	50 mm
G	Up to 500 kg	M42+	50 mm

Note: For Class B through E, door width may require an upgrade to a Class G top pivot (TP.G). The FritsJurgens Selector will confirm based on your door dimensions.

All floor plates are 80 mm in diameter or width and are compatible with underfloor heating installations. The floor plate shape and finish are selected at time of order. Flush (recessed) floor plates are designed for exterior-mounted door applications — required for drop seals and weather-tight threshold details.

FritsJurgens pivot systems are concealed inside the door and floor, with no visible frame or overhead closer. All systems use a bottom pivot, top pivot, ceiling plate, and floor plate. The right system depends on your door weight, whether you need self-closing, and how much control you want over door movement.

How to Choose

System ONE is a free-swing pivot with no self-closing and no hold positions. The door stays wherever it is left. Supports doors up to 500 kg with full 360° revolving capability. The simplest system in the FritsJurgens line — ideal when no closing force or position control is needed.

System M+ is the full-control system. Self-closes from up to 125°, with adjustable damping on opening and closing, a 30° slow-close zone, and Latch Control to ensure proper latching. Supports doors from 20 kg to 500 kg across eight weight classes. The right choice for most residential and commercial applications.

System FX combines free-swing movement with strong hold positions at 0°, 90°, 180°, and 270°. Opens in both directions and supports 360° revolving, but does not self-close. Suited to passages and open-plan spaces where the door needs to stay open.

All systems require milling into the door for the bottom pivot body. Floor plate options are shared across systems and can be surface-mounted or recessed into the sill.
